The ATB looks like a traditional but molded Rapid Robert, with a relatively flat bottom, pointed at one end and BIG square transom at the other end.
The Rapid Robert was meant to be powered from the flat transom with pointed end ahead, but rowed the other way around (without motor) with transom end downstream.
For power boats meant to at least SOMETIMES navigate in shallow water, slowly under power, the boats that do the best have a motor well in the rear, so the motor is surrounded by flotation, so the rear end doesn't dig down so badly when you goose the throttle.
Trim tabs can do that too. In the Bahamas I've seen at least two flats boats modified so they had small bolt-on pontoons either side of the motor, so it was almost like a motor in a motor well. The idea there too was to be able to twist the throttle in shallow water without the boat digging down at the rear (and standing vertical at the front) .
